Using screens an hour before bed increases insomnia risk and cuts sleep time, a Norwegian study finds.
A Norwegian study of over 45,000 young adults found that using screens for an hour before bed increases insomnia risk by 59% and reduces sleep time by 24 minutes.
The type of screen activity didn't affect sleep quality as much as the duration of use.
Experts recommend reducing screen time before bed and disabling notifications to improve sleep.
